Connecting
To connect to Microsoft Excel Online, you can use either a DSN or an ODBC connection string. Both of these methods use the odbcConnect function.
Connect to a DSN
To connect using a DSN:
cnx <- odbcConnect("CData ExcelOnline Sys")
Provide a Driver Connection String
To connect using an ODBC connection string:
cnx <- odbcDriverConnect(connection = "DRIVER={CData ODBC Driver for Microsoft Excel Online};")
